Urban biowaste, which refers to the organic fraction of municipal solid waste (MSW), is a predominant type of waste in low- and middle-income countries. Therefore, the sustainable management of urban biowaste is a key problem in solid waste management (SWM). However, treatment technologies usually come with secondary pollution and by-products that need further treatment, which would limit the economic and environmental benefits of the waste management system. The concept of industrial ecology has the potential to be introduced into the waste management field to solve this problem. Based on a practical case study of a city in eastern China, this paper conducted a complete urban biowaste treatment system planning exercise using concepts in industrial ecology. The establishment of the new system has significant economic, environmental and social benefits. The total output value of the project would reach 342 million yuan in 2025, corresponding to 945,000 tons of solid wastes consumed every year, which would significantly reduce the environmental pollution caused by solid waste. More than 700 jobs could also be created. In addition, the establishment of an urban biowaste sustainable management system requires the joint effort of enterprise, government and the public, which in turn requires innovation in business models and management policies. Therefore, a special management committee should be established to promote collaboration among stakeholders, and an online platform that enables end-to-end process supervision covering the entire system, including emergency management mechanisms, needs to be established to ensure the long-term stable operation of various treatment facilities. The results of this paper show that synergies among technologies should be promoted to provide systemic benefit, and that the infrastructure for pollution control should be shared to ensure high utilization.
城市生物废物是指城市固体废物(MSW)中的有机部分,是中低收入国家的主要废物类型。因此,城市生物废物的可持续管理是固体废物管理(SWM)的关键问题。然而,处理技术通常伴随着二次污染和需要进一步处理的副产品,这将限制废物管理系统的经济和环境效益。工业生态学的概念有可能被引入废物管理领域来解决这个问题。本文基于中国东部一个城市的实际案例研究,运用工业生态学的概念对城市生物废物处理系统进行了全面规划。新系统的建立具有显著的经济、环境和社会效益。该项目的总产值将在 2025 年达到 3.42 亿元,相当于每年消耗 94.5 万吨固体废物,这将显著减少固体废物造成的环境污染。此外,还可以创造 700 多个就业岗位。此外,建立城市生物废物可持续管理系统需要企业、政府和公众的共同努力,这反过来又需要创新商业模式和管理政策。因此,应成立一个专门的管理委员会,以促进利益相关者之间的合作,并建立一个涵盖整个系统的端到端流程监管的在线平台,包括应急管理机制,以确保各种处理设施的长期稳定运行。本文的研究结果表明,应促进技术之间的协同作用,以提供系统效益,并共享污染控制基础设施,以确保高利用率。
